When true, certain calculations may be deferred if the objects they reference are not in view. This applies to iterated calculation references only, such as UltraWebGrid rows. If possible, objects indicating that they are in-view will be calculated before objects that are out-of-view.
In some cases, deferring calculations is not possible. For example, if there is a footer on a column, then all the of the values in the column must have been calculated (and therefore cannot be deferred) before the footer value can be determined.
